CNN continues their coverage of MLK.  In this segment, why does Martin Luther King write his famous letters from a Birmingham jail?  In this segment the brush by the Birmingham church bombing

One thing that needs to be stressed is television.  Martin Luther King was the right person but so was Fredrick Douglass.  There were several Black leaders that were the right men or women.  Martin Luther King was successful because he was the right man at the right time.  He was in the era of television.  The Nightly News showed peaceful blacks marching.  The nightly news showed the dogs being turned loose.  It showed the fire hoses.  It showed King a man of peace verses those that wished to do him harm.
